What is a lumber takeoff?
A lumber takeoff is the count of every piece of lumber and framing material a project needs, pulled off the plans or measured on site. It is the lumber half of a full material takeoff. The output is a list, each line specific enough to order and priced by the piece: species, grade, treatment, dimension, and quantity.
The word "takeoff" just means you are taking the quantities off the drawings. On a framing job that means studs, plates, headers, joists, rafters or trusses, sheathing, and the fasteners and connectors that hold it together. Done right, the takeoff is what you hand to a supplier, or paste into a tool, to get a real price.
- Framing lumber: studs, top and bottom plates, headers, blocking
- Structure: joists, rafters or trusses, beams, posts
- Sheathing: wall and roof OSB or plywood, subfloor
- Connectors and fasteners: joist hangers, structural screws, nails, hurricane ties
- A waste factor: usually 5 to 10 percent on cut framing lumber
